Hi Rick & Bev,
Good advice, except the repack. Packing loads
into the gland as segments, not as a spiral
wound. The direction of shaft rotation has nothin' to do with it.
I found this very nice explanation to pass along.
this guy does a bang-up job of presenting this
task. Pages 2 & 3 is most interesting.

I suggest performing this task during a haulout
and using the shaft near the propeller as your
packing segment cutting guide. It's a very comfortable way to do it.
I didn't see it there but a properly adjusted
stuffing box with flax & lanolin packing (the
common old timer's marine stuff), will drip once
per second at running speed and dry up when it cools.
Cheers, Russ

HI Bev, I now have a dripless shaft, but in the
past I have tweaked these. Itâs not
complex. If you donât need new packing you
just tighten the gland to a point where it is
weeping at the rate you like. Channel locks or
pipe wrench will do the trick. This is not high
stress wrenching but you need to tension the
packing with the first large nut, and then lock
your tension with the second net to snug. Too
tight on the packing and it will heat up and eat
the packing pretty quickly, so the whole
exercise is gentle and to be happy with the rate
of drip. If you tighten it down and the pace
continues, you may need new packing. If you pull
your old packing out a bit and snip some off to
see what was used you should be able to staunch
the flow again. If you pull it all out the box
will leak at a high rate. Lots of folks have
the new packing! Plan accordingly. As I recall
the new packing wraps in the opposite direction
as the forward prop spin (take a mental picture
as you pull the old packing out), enough to fill
the gland then tighten gently to the point the
drip slows, stops or is very small. Keep an eye
on it and tighten accordingly. It will break in
eventually and will remain static possibly for
years. I wish I were in Vancouver as I would
drop in and fix it, for a couple of pints. Of
course in Canada it may be cheaper to hire a top
notch mechanic than buy me a couple of beers. lol
It sounds like you are worried about it, and
rightly so as the relentless dripping adds up in
the bilge. It is not a huge problem though and
someone on the net will chime in and come give
you a hand. Great folks in BC on C&C and other fine vessels.

What is the size of nuts on the stuffing box
shaft? What size is the packing? Does anyone
know of a gnome or elf available for hire in Vancouver to tighten the same?
